' cation.'

The presentinventionrelates to improvements in latches, particularly latches for automobile doors, and has for an object to provide a latch which' may be locked from the inside of the door in such manner as to prevent operation of the handles, but will at the same time allow the bolt to be freely pressed into retracted position when the latch is locked. An advantageof this feature is that in the event of accidentally locking the latch in the open position of the door, the bolt will be free to press back when closing the door, otherwise it would forma dead stop with the possibility of injuring the latch and door structure.

It is further proposed to provide a unitary locking device adaptedto lock both the roll back handle and the lever handle in the case of those latches provided with two such handles and it is also an object to providea locking attachment suitable for use on a latch `of known construction without requiring material change in the latch, and which will not in any way interfere with the normal operation thereof.

The latch, according to my invention, is particularly intended for'use upon closed automobiles having four doors, its purpose being to allow the owner of the automobile to lock the latches upon; three of the doors upon the inside before heleaves the car and lock one of the doors from the outside thereby locking all the doors by the actual'locking fromthe outside of one latch. l A

With these and other objects in view, embodiments of my invention are shown in the accompanying drawings and these embodiments will be hereinafter more fully de- Vscribed with reference thereto and the invention finally pointed out in the claims. -In the accompanying drawings, AFigure 1 isa plan view of a latch embodying my improvements; Fig. 2 is an Vend elevation; Fig.

i l 3 is an enlarged detailed sectional view of the plan view of a modified form of latch embodying my improvements; and Fig. 6 is an end elevation thereof.

Similar reference characters indicate corresponding parts throughout the Vseveral figures of the drawings.

,Referring to the drawings and more particuiarly to Figs. 1 to 4 thereof, the embodiment of my invention shown therein consists of'a latch comprising `a base plate 10 provided at its forward edge with the face-portion 11 bent outwardly therefrom and having mounted thereon a reciprocating bolt 12 having its nose projected through an opening 13' in the face 11. Its inner end is slidably disposed in an opening 14 of an angular frame piece 15 secured to the plate 10. The bolt is normally pressed forward by a coil spring 16 mounted on the plate 10 and is adapted in the usual manner to be forced back against the force of the spring in closing the door.

Upon the upper side of the bolt there is I formed an extension arm 17 adapted to be engaged by'a roll back lever 18 rotatably mounted between the plate 10 and frame 15 and connected in the usual manner 'to the outside of the door of the automobile, being l provided for this purpose with a square opening 19 extending therethrough. In order to prevent rattling of the roll back lever 18 and the handle connected thereto, and prevent any looseness therein when the bolt is not fully projected, and at which time the lever arm 17 would not positively force the roll back against the face plate, there are provided spring means cooperating with the roll back to hold the same yieldingly and in engagement with the face portion 11. Thesemeanscomprise a guide rod 20 pivotally connected at the one end 21 to the roll back, and slidable at it-s other end through a bracket'22 formed upon the frame 15, a helical spring 28 being mounted upon the rod, bearing at one end upon an enlargement 24 .thereof and at Vthe other end upon the bracket 22. The bolt is also adapted to be retracted independently of the roll back 18, by means of a lever 25 pivotally mounted at 26 upon the plateV 10 extending through a cutout portion-27 of the bolt and engaging a lug 28 thereofyat one side, itsother side engaging a stopor abutment 29 formed upon the frame 15, the lever being normallyV held yieldingly in its position against the stop 29 by means of a spring pressed plunger 30 mounted upon of the retraction movement of the bolt by direct pressure thereon in the closing movement of the door.

3. In a latch, a reetilinearly movable latch bolt, primary and secondary independently operable means for retractng said bolt, and means common to both of said retraction means to lock one or both of such retraction -means against eiective operation.

operative path of said retraction meansto prevent operation thereof, said bolt adapted to be retracted independently of said last named means, and secondary retraction means adapted to retract said bolt independently of said rst mentioned retraction means and also adapted to be locked against operation by said locking means.

In testimony that I claim the foregoing as my invention, I have signed my name hereunder.

LEON OTTINGER.
